* PM to meet opposition leader, cabinet meeting to follow
* Media say measures may include wage cuts, taxes
LISBON, May 12 (Reuters) - Portuguese Prime Minister Jose Socrates will meet the leader of the main opposition party on Thursday to discuss additional austerity measures, which the cabinet may approve in a weekly meeting later the same day.
The prime minister's office said on Wednesday Socrates would meet Pedro Passos Coelho, the leader of the centre-right Social Democrats, at 9:30 a.m. (0830 GMT) on Thursday.
Passos Coelho has said he proposed to the government a range of measures to deepen budget deficit cuts in order to soothe investor concerns, which have hammered Portuguese assets since January, that Portugal may face a Greek-style debt crisis. Finance Minister Fernando Teixeira dos Santos told Reuters on Wednesday the government had identified a set of austerity steps to be taken but needed to consult the PSD "to create conditions for carrying them out". Officials say there is no need to resort to a trillion-dollar euro zone safety net approved on Monday by euro zone governments, the European Central Bank and the IMF.
Socrates' Socialists are ruling in a minority government and need the support of the opposition to pass bills in parliament.
Over the weekend, the government promised to cut this year's deficit by an additional percentage point to 7.3 percent of GDP and next year's gap by an extra 1.5 percentage points.
Teixeira dos Santos said new measures would focus mainly on spending cuts but may also include tax hikes if needed.
State-run Lusa news agency cited an unidentified government source as saying one of the proposals includes a 5 percent wage cut for public companies' managers and politicians.
TVI news channel said the government was also preparing an extraordinary 1 percent tax on salaries below 2,375 euros ($3,017) a month and 1.5 percent on higher wages, while the value-added tax rate may rise to 21 percent from 20 percent.
It said major companies and banks would also pay an additional 2.5 percent tax on profits. TVI said the measures should enable the deficit to be cut this year by an additional 2.1 billion euros to 7 percent of GDP. (Reporting by Andrei Khalip, editing by Mark Trevelyan)
